Abstract: A frame supports heat exchangers one in front of another in the direction of flow of cooling air, and includes two vertical walls interconnected by transverse walls, cross braces between the walls, and fastening points on the walls adapted to fasten the heat exchangers to the frame. Outwardly extending bulging sections in the vertical walls include an outer portion adapted to be secured to the vehicle support members to support the frame thereon, and an inner portion defining a space between vertical wall sections above and below the bulging section for receive projecting components of at least one heat exchanger. Connectors connect each of the fastening openings to the aligned flange openings, with the connectors including a head and a stem with an expandable end opposite the head retaining the connectors in the aligned openings. Hooks support the heat exchangers in the direction of air flow, with the connector stems supporting against at least some forces transverse to the direction of air flow.
